DOOR-STOP.

Specification of Letters Patent.

Application filed March 21, 1908.

Patented Dec. 1, 1908.

Serial No. 422,394.

To all whom it may concern:

Be it known that I, DANIEL A. FIES, a citizen of the United States, anda resident of the city of Reading, in the county of Berks and State ofPennsylvania, have invented certain new and useful Improvements inDoor-Stops, of which the following is a specification.

My invention relates to door stops of the type in which aspring-operated catch is cooperatively combined with the stop, asindicated in Patent No. 646,533, of April 3rd, 1900; and it consists incertain improvements in construction which are fully described inconnection with the accompanying drawings and the novel features ofwhich are specifically pointed out in the claim.

Figure 1 is a longitudinal sectional view of a combined stop and catchembodying my invention. struction and, Fig. 3 is a longitudinalsectional view of a fragment of the invention sholwing the springcompressed by a key or too The hollow stop-body a is formed in one pieceas shown, with the central bore thereof providing a spring-chamber 1)opening through therear end, and a smaller diameter portion 0 openingthrough the front head for the passage of a buffer-device d; said devicebeing inserted from the rear end of the stopbody and having a circularflange 6 seating against the annular shoulder f formed in the bore. Thisbuifendevice is positively held against removal through the frontopening 0 by its flange e, and is also, as indicated in Fig. 1.,positively held against rearward movement by a rear shoulder 9 formed inthe bore between which latter and the shoulder f the flange e of thebuffer-device is retained.

The introduction of the latter to the position described is readilyprovided for by making it of rubber or like yielding material, so thatthe flange (2 may be readily forced through the main bore 6 of thestop-body and thereafter spread out between the shoulders f and g asindicated.

The catch is which is employed in connection with the stop a to engage akeeper device m on the door in the manner indicated in Patent No.646,533, previously referred to,

Fig. 2 indicates a modified con-' is similarly engaged in a longitudinalslot n provided in the wall of the stop-body a, and also hasanapproximately right-angled footportion p which extends into the bore band is pressedupon by a spring g in the latter to normally hold thehooked outer end 1" of the catch in keeper-engaging position. In myimproved construction this foot-portion p of the catch is ofsubstantially the same width as the slot 72, in the stop-body, so thatit may be introduced laterally to the bore 1); and it is formed with aspring seat 10 adapted to so engage the bottom of the spring q as to belocked by the latter against removal when the parts are assembled. Toeffect this assembling and thus lock the catch, the 5 ring 9 after beingplaced in the bore throug the rear end of the stop-body, is compressedby a suitable tool so as to ermit the introduction of the catch-foot pthrough the slot n to position under the spring, which latter is thenreleased and engages the foot under suitable tension so as to firmlyretain it in the bore 1) and at the same time press the hooked outer end7* towards the head of the stop. The inner end of the spring isreferably covered by a loose washer .9 intro uced into the bore 1) aheadof it as indicated.

As indicated in Fig. 1, the stop is formed with a securing flange t atits rear end for attachment to a washboard or base-board; or it may beprovided with a floor-support t as indicated 1n Fig. 2. In either 0ening or closing the door the catch is move outward by forcible contactwith the keeper 1% against the tension of the spring, as is wellunderstood. In opening the door the shock of sto ing it is taken by thebuffer-device d, Wlllc fl in addition to being positively held againstundue yielding movement by the shoulder g is also yieldingly supportedby the spring If desired the positive stop for the bufier device whichis provided by the shoulder 9 of the preferred construction described,may be omitted, the spring q furnishing necessary su port as indicatedin Fig. 2.

What claim is 2- A combined door stop and catch com rising a hollow bodyopen at one end and aving a slot in the wall thereof, a catch having afoot portion extending through said slot into the hollow body, and aspring in the hollow In testimony whereof, I aflix my signature, bodyengaging the foot portion andseeuringf in the presenceof't'wo'witnesses. the catch inposition under tension, said DANIEL AFIES spring extending beyond the side of the foot 5 portion whereby a,-tool may be inserted Witnesses:

through the said open end of the body to DFM. STEWART, compress thespring. W. G. STEWART.
